Letters Patent No. 94,660, dated September 7, 1869.

IMPROVED DEVICE FOR PUMPING-BY THE MOTION OF THE CARS.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom 'it may concern:

Be it known that we, ROBERT R. vSPEDDEN and E. CLIFFORD SPEDDEN, of Astoria, in the county of Ola'tsopand State of Oregon, have invented a new y and improved Device for Pumping by the Motion of the Oars; and we do hereby declare that the followingis a full, clear, and exact description'thereof, which will enable others skilled in the art to make and use the saine, reference being had.to the accompanying drawing, forming part of this specicatiou.

The drawing represents a side view of an apparatus adapted to pump by the motionof the oars.

This invention has for its object to pump a boat `by the motion communicated to the oars in the operation of rowing.

One means of carrying this into eject is shown in the accompanying drawing, although suitable other means may be employed for the same purpose.

The pump to be used may be of any suitable construction, and its stroke greater or less, according to the size of the boat; perhaps in no case more than four inches, and as little, in some, as two. l

On ships boats, surf-boats, and, indeed, on all boats so exposed as to be liable to ship water, in most instances when the sea is rough enough to cause a boat to ship water, it is impossible to bail her, asit requires all hands at the oars, and if loaded with people, as in case of wreck, or other marine' disaster, there is no possible chance to bail.

The apparatus is so constructed that the pumpingconnection can be locked or thrown 'out of gear when there is no necessity for pumping.

The invention consists chiefiy in arranging a sliding row-lock, which will be moved back and forth on the gunwale of the boat, whenever the oar is used, and which by such motion will operate, by suitable c'onnection, a pump for discharging water from the boat.

The invention consists also of the particular` apparatus which we represent as one mode of carrying our main invention into effect.

A, inthe drawing, represents the side of a boat.

B is the gunwale of the'same.

O is the row-lock.

'.Lhe same projects from a plate, D, which is fittedbetween ears g g, that project from a plate, E, fastcned to the 'unwale, so that said plate D can move backward and4 forward with the row-lock on the fixed plate E.

From the under 'side of the plate D projects, through a slot of the `gunwale, a pin, a, which is fastened to the piston-rod b of a pump, F, as shown.

The pump F is arranged iu a suitable part of the boat, and has a suction-pipe, c, reaching to the bottom of the boat, and a discharge-pipe, d, extending through the side of the same.

A spring, e, is fastened to the pin a, which,` when compressed, will push the said pin toward the pump.

The object of this spring is not only to return the pump-piston, after it has been drawn Qutby the power applied to the oar, but also to so resist the sliding motion of the plate D that the oar in the row-lock will bear with its full force on the water, whilst the rowlock is being forced forward by the power applied by the oarsman.

It will be readily understood that the row-lock will,

when the oar is worked in it, be moved forivard, to

give one stroke of the piston, and that the spring will, when thus compressed, force the row-lock back again, and produce the other stroke of the piston, while the oar is-swung back out ot' water.

A plate, f, is hinged in front of the plate D, to the gunvale, and can be swung down, as shown by led lines in the drawing, when it is desired to lock the said plate, to stop thepumping-operation.

Instead of this plate f, a simple pin, itted through the gunwale infront of the plate D, 0l' any other equivalent device, may be used.

We do not confine ourselves to the particular apparatus herein described, for utilizing the motionof the oars to empty the boat of its water; but i We do claim as new, and desire to secure by Letters Patent- 1. A sliding row-lock, connected with a pumpingapparatus, so that it may, during the operation of rowing, serve to operate the pumping-apparatus, substantially` as herein shown and described. v

2. The row-lock C, when fastened to a sliding plate, D, which is, by a pin, a, connected with the pistonrod of a pump, substantially as herein shown and described, to operate as set forth.

3. The spring e, when connected with the sliding row-lock, for the purpose of partly counteractng the forward motion ot the row1ock,'and for returning the pump-piston, substantially as'herein shownand described.

4.. The hinged plate f, or its equivalent, when arranged to lock the sliding row-lock, substantially as herein shown and described, for the purpose 'of' arresting the pumping-operation,"as specied.
